Water heaters are invaluable equipment for any household. In order for your water heating system to remain functional and have a long lifetime, you need to do proper upkeep. Here is a maintenance guide, which provides useful information on water heater maintenance.
Flush the tank at least once or twice a year
There should be a water drain located at the bottom of your water heater. This is where you will attach the hose or just place a large bucket that will be able to contain the dispersed water. If you plan on using a hose, avoid putting its end on a landscape on your lawn since the hot water can kill the grass. Don’t forget to turn off the water heater and other main components before the flush commences. Once everything is in place you can switch the valve to release water.
You may be wondering why you should go to all this trouble to drain water out of the tank. The reason for this is to remove the sediments that are lingering at the tanks bottom portion. These sediments are a real threat to your water heater since it can slowly puncture the tank. This can lead to leaks, which poses as a serious problem. If there are a lot of sediments from the drained water then you need to flush the water out repeatedly until there is nothing left.
Inspect the anode rod and replace it if the rod is too corroded
The anode rod is a crucial part of a water heater. This rod is the very reason why your water heater doesn’t corrode easily and stops other forms of metallic deterioration from happening. The rod sacrifices its metal components so that it can absorb the rust — protecting the other parts of the heating system from degradation. Check the anode rod after 2 years since its installation for corrosion. An anode rod that has a few mineral deposits is normal but if you noticed that it’s dominantly corroded then you need to replace the rod.
The anode rod is usually found at the top spot of the water heater while others are placed at the side of the tank. You can identify it with its hexagonal cylinder. Wrenches can help you remove the anode rod with ease. Be careful when removing a rusted rod since it might hit some parts of the tank and shed off rusty debris.
Make sure the pressure-relief valve is working
The pressure-relief valve is a safety mechanism that releases water if the water heater can’t bear the water and pressure inside the tank. Your water heater is in big trouble if the pressure-relief valve stops working since the pressure will just keep building-up — and possibly cause an explosion.
You need to do some maintenance checks with the valve. Place a bucket below the valve before doing the inspection. Pull the lever above the pressure-relief valve and it should be able to release the water. If there is no water coming out, then this is a clear indication that the valve isn’t working.
